 RLS-0071 is ReAlta’s lead dual-action complement inhibitor and innate anti-inflammatory peptide in development as a treatment for hypoxic ischemic encephalopathy, severe asthma, and other rare diseases

 Norfolk, VA, June 23, 2022 – ReAlta Life Sciences (“ReAlta”), Inc., a clinical stage, rare disease company dedicated to harnessing the power of the immune system to address life threatening diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to RLS-0071 for the treatment of hypoxic ischemic encephalopathy (HIE). RLS-0071 is the Company’s lead dual action complement inhibitor and innate anti-inflammatory peptide.

“Based on our compelling preclinical data and the strong safety profile established in our Phase 1 Healthy Volunteers study, we believe we have an opportunity to radically change the way we treat HIE and other rare diseases,” said Ulrich Thienel, CEO of ReAlta. “The designation of Fast Track is a testament to the unmet need in HIE and will support a closer collaboration with FDA  on our clinical development plan and work to earlier drug approval and access by patients.”

Fast Track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. Benefits of this designation include more frequent meetings with FDA to discuss the drug’s development plan and ensure collection of appropriate data needed to support drug approval, as well as more frequent written communication to discuss aspects such as the design of the proposed clinical trials and use of biomarkers. A drug that receives Fast Track designation may also be eligible for Accelerated Approval and Priority Review.

HIE, also known as birth asphyxia, is a rare disease that affects newborns suffering an abrupt, unexpected loss of oxygenation due to placental rupture, umbilical cord problems, or other factors.   The initial loss of oxygen and the dysregulated inflammatory process that follows causes damage to the brain and other organs. This acute disease often results in death or moderate-to-severe cognitive and physical disability, with life-long impacts on both the newborn and the newborn’s family.

RLS-0071 is a 15 amino acid peptide that both inhibits humoral inflammation by blocking classical pathway complement activation and cellular inflammation by blocking the neutrophil effectors myeloperoxidase (MPO) and neutrophil extracellular traps (NETs).

ReAlta Life Sciences, Inc. is a clinical-stage, rare disease biotech company dedicated to harnessing the power of the immune system to address life threatening diseases. The Company’s EPICC peptides are based on research into the human astrovirus HAstV-1, which causes a non-inflammatory, self-limiting gastroenteritis unique among viruses by inhibiting components of the innate immune system. ReAlta’s therapeutic peptides leverage these virus-derived mechanisms to rebalance complement and inflammatory processes in the body. The company’s pipeline is led by RLS-0071, which has received IND clearance, and Orphan Drug Designation by the U.S. Food and Drug Administration and European Medicines Agency for the treatment of hypoxic-ischemic encephalopathy (HIE) in neonates.
